To all whom it may concern:-

' Be it known that we,'JAnns THOMSON andERNE'sr SCHWAMBERGER, citizensof the United States of America, residingA at Pittsburg, in the'countyof Allegheny and State of Pennsylvania, haveinvented certain` new anduseful Improvements in Motors, of which the fol'- lowing is aspecification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful inn-v provements inmotors, and more particularly. toA that type employed in connection withbrushes, for cleansving flues and the like tubes.

The invention has for its object to provide a novel form of motor, whichwill be extremely simple in con-A struction, strong and durable,comparatively inexpensive to manufacture andhighly eicient in operation.

The invention aims to provide a motor having a ballA bearing stemmounted therein, and novel means for ,revolving said stem, when a supplyof fluid such as water is admitted to said motor. The constructionemployed lin connection with motors heretofore used, has been vextremely expensive, and the primary'object of this invention is to'provide a construction in connection with a motor which can be readilymanufactured `and used without incurring much expense. i

' Withithe` aboveandother objects in view, the invention consists in thenovel construction, combination and arrangement of parts which will behereinafter more fully described', andthen specifically pointed .out inthe claims, and referring to the drawing ac- `cornpanying thisapplication, like numerals of reference designate corresponding partsthroughout the several views, in which:-- v

Figure l is a side elevation of amotor constructed in accordance withour invention, Fig. 2 is a top plan view thereof, Fig. 3 is a verticalsectional view thereof, Fig. 4 is a detached detailed view of the waterwheel and a portion of its stem, Fig. 5' is a top plan view of the waterwheel, with the stern thereof in section, Fig. 6 is a detached detailedside view of the stationary head of `the motor, Fig. 7 is a bottom planview of the same, and Fig. 8 is a transverse sectional View taken on theline x-x of Fig. 3.

To put our invention into practice, we employ a cylindrical casing l,the one end of which converges toa closed tapering cud 2. .This end ofthe casingis provided with a plurality of circularly disposed slots 3,3,

which are preferably formed near the periphery of the casing l.Centrally of the end 2, we provide an opening 4 and the 'materialforming ythe end 2 is cut away to inafter described.

within said casing is al shaft `*The one end of the shaft 8 carries acollar 9, adjacent to its screw threaded 'end'1( this end protrudingthrough the opening/4 of the 'casing 1. yThe collar forms a race forlthe ball bearings l1. The opposite end of theishaft 8 is provvidedl witha plurality of vstepped reduced portions 12, '14v and15, the reducedportion 15 forming the extreme end of the shaft 8. The referencen meral16 designates a tapering collar carried the shaft 8 adjacent to thereduced portion r Upon the reduced portion l2 is secured the water wheel17 illustrated in Figs. 4 and 5 of the drawing. This wheel'is providedwith a plurality of peripherally curved grooves 18, said grooves whendeveloped being substantially wedge shapedand disposed tangentiallyto'the verticaljaxis of said disk.A The marginal blades or vanes 19 onthe bodyof the wheel are each cutaway at their larger ends, as indicatedat 2O forming a.

beveled surface, kwhich increases the size of the entrance of saidgrooves, the object of which will be here- Secured in the screw threadedend 7 of the'casing 1, is a stationary head 2], said head being providedwith a central opening 22 that engages over the reduced portion 1'4 ofthe :haft 8. The head 21 is 'provided with a depending annularinteriorly'screw threaded ,flange or-collar 23. The peripheryof the head2l is provided with a plurality of curvedgrooves 2l formed similar'tothe grooveslS of thewheel 17, with the exception that said grooves aredisposed tangentially the reverse ofthe grooves 18 formed inthe wheel17.

.The periphery of the head 2l is screw threaded as indicated at 24,whereby the casing l. v

The reduced portion 14 of the shaft 8 forms one wall of a ball race 25and in the screw threaded collar 23, we

thehea'd can be fixed within secure a cap 26 having a tapering seat 27formed therein forming the other wall of said ball race425,`and in saidrace we mount a plurality of -ball bearings 28. The l cap 26 is providedwith a peripheral flange 29 and when securing said cap within the collar23', we preferably employ a washer'SO, which is interposed between thecollar 23 and the flange 29.

' The reference numeral 3l designates a collar which is exteriorly screwthreaded. as indicated at 32 and interiorly screw threaded as indicatedat 33. The collar is secured in the screw threaded end 7 of the casing land serves functionally two purposes, namely, as a jam nut for the head21 and a union forv the pipe connection to be made with the motor.` I

Thev device is particularly adapted to be lused in 'connection with abrush not shown) that' is mounted upon the screwv threaded end l0 of theshaft 8, also with a suitable water supply pipe, (not shown) which isconnected to the collar 31.*. As the water passes through the collar 31it passes through the grooves 21 and is tangentially discharged againstthe Wheel 17. The water encountering the grooves lS'of said Wheel,causes the same to revolve, on account of the Water being dischargedtangentially to said Wheel and encountering the heveled surfaces 20ofthe blades or vanes 19 of the Water Wheel. The revolving of the Wheel17 'causes the water to be disch-a led within the casing in a spiral orcircuitous path, the Water being finally discharged from the casingthrough the slots 3 formed in the contracted end of said casing. Thedischarged Water then encounters a brush carried by the shaft 8,-

and as said shaft is being rapidly revolved hy the passage of Waterethrough the Wheel l7, thc fines in which' said brush is being retainedwill be thoroughly cleansed of any foreign ingredients that may adhereto said llues.

By mounting the shaft 8 in hall hearings, We have reduced the frictionineurredvloy the rotation of the shaft, to a minimum, at the satiretime, maintaining a journalI shaft which will transmit the revolublemotion impartedI to it by the Water wheel 17,- to the brush or brusheswhich it carries.

While We have herein shown the preferred manner 'of constructing ourimproved motor il; is obvious that various changes may be made in thedetails of consi ruction Without departing from the general spirit andscope of the invention.

What We claim and desire to secure by Letters Patent, isz- A device otthe class described, comprising,- a cylindrical casing internallythreaded at one end and reduced at the other end and with a hearing' inthe reducedtportion and with discharge ports at the juncture ot' thereduced portion and the hody of the casing'. un lexternally threadedannular member engaging the threaded portion of the easing, :inf1 with aplurality of angular recesses in its periphery and transversely of itsthreads, said annular member havingr a projecting: annular sleeveinternally threaded, a collar hav ine' means ar one end for connectingto the source of power and with a threaded portion at the other endengagim;l the threaded portion of said casini;- exterior-ly of saidannular moniher and with a central shaft step externally threaded andengaging the threaded sleeve or' the annular' member, :i shaft mountedfor rotation through the hearingY :it the reduced end of said casinaYand suppoired in said stepat the other end, and a water wheel havim.Yspaced peripheral blades and connected tn said shaft adjacent to saidannular member.
